The Bubble Nebula & M52

Interesting area of the sky! There's a lot going on here between the Bubble Nebula (on the lower right side), other nebulosity including NGC 7538 (top center) and the open star cluster M52 (bottom center). I was looking for a target that I could get on right at astronomical dark and image until around midnight without losing time to a Meridian Flip. NGC7635 and M52 were perfectly positioned for my backyard. This image is only about 4.5 hours of 5-minute sub exposures. Even considering the short integration time, the impact of a nearby half-moon I am pretty happy with the result. As a side note Guiding on this night was extraordinary. I was able to maintain a total error of well below 1 arc second.

NGC7538 is home to largest protostar to yet be discovered. A protostar is a very young star that is still gathering it's mass from the surrounding dust clouds. In the case of NGC7538 it is thought that it's size is 300 times the size of our solar system.

The Bubble is worth zooming in on a bit. A very odd structure in space. The bubble is the result of stellar winds emanating from a bright young star (SAO 20575). Here's what blows my mind, I captured this image using a small (72MM) refractor and a modern CMOS camera riding on a precision guided Equatorial Mount. Even at a focal length of around 350MM you need to zoom in to really see the bubble. How in the World did William Herschel "discover" it (and a ton of other deep space objects) in 1787?

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
